Problems solved by technology

However, the data modelled, based on a particular standard is not accessible to systems that use data modelled, based on another standard.
This limits interoperability between systems that use data modelled, based on different standards.
Generally, the amount of data to be converted is large.
This makes the mappin

Embodiment Construction

[0021] Data exchange between systems and applications can be based on International Electrotechnical Commission standards, e.g., IEC 61970 and IEC 61850, for the interoperability and integration of such systems. The data exchange involves conversion of data based on IEC 61970 to IEC 61850, and vice versa. This involves a syntactically and semantically correct conversion and mapping of the data objects of IEC 61970 and IEC 61850. A system, a method and a computer program product are disclosed to semi-automatically perform the conversion.

[0022]FIG. 1 schematically depicts the basic elements of a utility control system, according to the exemplary embodiments. Utility control system 100 comprises a system 102 with data modelled, based upon IEC 61970, and at least one system 104 with data modelled, based upon the IEC 61850 standard. In an exemplary embodiment, system 102 is a control centre system and system 104 is a Substation Automation System (SAS). An exemplary semi-automatic conver...

Abstract

A system and method of converting a file is disclosed that is based on a first standard to a file that is based on a second standard. The concerned standards can be IEC 61970 and IEC 61850 or their equivalents. For conversion, a file based on IEC 61970 is coded according to CIMXML (RDF Schema), and a file in IEC 61850 is coded according to SCL (XML Schema). The data in each file is modelled by using a UML model for the corresponding standard. The method includes the automatic generation of mapping rules that can be based on the UML models of the two standards and the mappings between the two standards. The method further converts the identified elements by using the generated mapping rules. Finally, post-processing rules can be applied to the converted elements to generate the file, based on the second standard.

Description

RELATED APPLICATIONS [0001] This application is a continuation application under 35 U.S.C. §120 to PCT / CH2004 / 0005 10 filed as an International Application on 16 Aug. 2004 designating the U.S., the entire contents of which are hereby incorporated by reference in their entireties.FIELD [0002] The disclosure relates to utility control systems in substations and control centres, and, more particularly, relates to conversion of data between IEC 61970 standard and IEC 61850 standard, and vice versa. BACKGROUND INFORMATION [0003] Utility control systems in Substation Automation Systems (SAS) and control centres in a power system network together serve to monitor, supervise, control, and protect the power network to economically provide high quality electricity in a reliable manner. The operation of the power system network can be improved by ensuring a higher degree of integration of control centre applications and SAS applications. The integration requires exchange of data between SAS an...
